Toledo, Ohio, assignor to Owens-Illinois Glass Company, a corporation ofOhio Application February 1, 1937, Serial No. 123,370 7 Claims. (01.215-31) The present invention relates to dispensing containers and morespecifically to bottles of the type employing a threaded closure or capand having a pouring lip ing of the liquid contents of the bottle duringpouring thereof.

It is an object of the presentin vention to provide a bottle having arestricted pouring lip which is independent of the threads formed on thebottle neck, which in no way interferes 'with their normal action, whichwill permit the use of threads of longer efiective length, and whichprovides a continuous sealing surface around the mouth of the bottle forengagement by the usual threaded closure.

It is another object of the invention to provide a bottle having arestricted pouring lip on the neck portion thereof, which bottle isreadily adaptable to the usual forming operations in bottle machines ofthe Owens type without requiring special operations and withoutnecessitating increasing the over-all diameter of the bottle neck ordecreasing the internal diameter thereof or in any other mannerrestricting the mouth opening in order to accommoutilize standard sizecaps.

It is another object of the invention to provide a bottle which iscapable of efiicient use in the dispensing of cough syrups and othermedicines in teaspoon or tablespoon quantities and which, toward thisend, is provided with a pouring lip having associated therewith meansfor guiding the edge of the teaspoon or tablespoon thereagainst in orderthat the lip shall overlie the edge of the spoon during the pouring ofthe liquid from the bottle, thus minimizing the effort required (by aninvalid for example) to dispense measured quantities of the liquid fromthe bottle.

Still another object of the invention is to provide a bottle which isalso capable of efiicient use in dispensing medicines in drop quantitiesand which, toward this end, is provided with a pouring lip having arounded edge which will reduce the tendency of liquids to adherethereto, thus insuring clean separation of each drop from the succeedingone in the drop-by-drop dispensing of liquids.

Other objects of the invention will become more readily apparent as thedescription ensues;

In the accompanying drawing:

Fig. 1 is a side elevation of the neck portion designed to minimizespillof a bottle manufactured in'accordance with the principles of thepresent invention;

Fig. 2 is another side elevation thereof;

Fig. 3 is atop plan viewjof the bottle; and

Fig. 4 is a sectional view taken substantially along the line l 4 ofFig. 3.

A bottle is designated at reduced neck portion H the sides of which aresubstantially cylindrical. Threads I2 are formed on the neck toaccommodate the usual threaded cap or closure (not shown). A shoulder I3is formed on the neck I I below the threads I2 to limit the downwardmovement of the cap.

The helix provided by the threads I2 is interrupted at the points l4 anda portion of the glass extending between the ends of the interruptedthreads I2 is cut away as at I5 to provide an inwardly and upwardlyinclined plane surface I6 which terminates slightly below the level ofthe mouth of the bottle I0, thus providing a restricted rounded pouringlip I! which overlies the cutaway portion I5. The plane surface I6 ofthe cutaway portion I5 is in effect formed by the intersection of aninclined plane surface with the cylindrical neck I I as determined bythe provision of a suitable insert in the mold in which the bottle I 0is'formed. The surface I6 extends from an elliptical end point I8 on thecylindrical surface of the neck I I upwardly and inwardly, diverging inwidth along the elliptical lines of intersection I9 and terminating ashort distance below the level of the bottle mouth. The interrupted endsI4 of the threads I2 are rounded and terminate substantially at theelliptical lines of intersection l9, thus barely providing clearance forthe cutaway portion I5.

From the above description it will be seen that the thickness of thebottle neck wall is not reduced throughout any material extended area ofthe bottle neck and the bottle neck is not rendered fragile by virtue ofany weakened region thereof. I

Furthermore, by such a construction, the effective length of the threadsis increased by a linear distance equal to at least the width of thesurface I6 at the elevation of the threads In dispensing liquids inteaspoon or tablespoon quantities, the surface I6 assumes the functionof a guide for the edge of the spoon in order that the edge of the spoonmay be brought into engagement with the pouring lip I1 with the latteroverlying the edge of the spoon. Thus, invalids will not find itdifiicult to dispense medicines inasmuch as they will not be obliged toaccurately align the edge of the spoon with the III and includes arestricted region that normally exists between the top of the threadsand the underneath side of the pouring lip but may slide the spoon edgeupwardly through the threads until they locate the pouring lip.

'In dispensing liquids in drop quantities, the

rounded edge of the pouring lip l1 reduces the tendency of liquids toadhere to the lip and thus, clean separation of eachdrop from thesucceeding drop in the drop-by-drop measuring of liquids is facilitated.

The extreme upper rim of the bottle mouth'is not disturbed by theundercut portion-l5 below' pouring lip, said lip being contained whollywithin the cylindrical confines of said bottle neck, said screw threadsbeing interrupted medially of their ends to accommodate said undercutportion of the bottle neck.

2. In combination, a bottle including a neck defining a filling anddischarge opening and having concentric cylindrical inner and outersurfaces, said neck having a continuous annular sealing surface ofuniform width at its outer end, external screw threads on said neck,said outer surface of the bottle neck being provided with a cutawayportion having a plane upwardly and inwardly inclined surface below therim of said neck providing an outwardly extending lateral restrictedpouring lip at the mouth of said bottle neck, said pouring" lip beingcontained wholly 'wit-hintheo cylindrical confines of said neck, the

thickness of the neck wall in the lower regions of said cutaway portionbeing greater than the thickness-{of t-he wall in the upper regions of,said cutaway portion, the width: of said" cutaway POT-r tion in thelower regions; thereof being less than the width thereof in the upperregions. thereof, said screw threadsbeing interrupted medially of theirends to accommodate said cutaway por tionof the neck.
